Embodiment 1

[0087] Figure 5 It is a schematic flowchart of the first method of the load reporting method between the UMTS system and the LTE system in the embodiment of the present application. In the prior art load reporting methods, such as image 3 As shown, the RAN information request message sent by the RNC of the UMTS system includes: source cell information, destination cell information, and RIM container. The format of the source cell information and the destination cell information is the same, and is indicated by RIM routing information. In this embodiment , collectively referred to as RIM routing information, the RIM container contains cell unique identifiers of multiple LTE cells that need to report load information, and these LTE cells belong to the same eNB.

[0088] The main idea of ​​the first method in this application is: when multiple LTE cells that need to report load information belong to different eNBs, that is, when they belong to multiple eNBs, the RNC of the UMT...

Embodiment 2

[0095] The second embodiment describes the process in which the RNC requests the eNB to report the load information of its cell. The process of the eNB requesting the RNC to report the load information of its cell is similar to the second embodiment, except that the source node is replaced by the corresponding node of the LTE system, the destination node is replaced by the corresponding node of the UMTS system, and the message name is changed accordingly. I won't go into details here. see below Figure 6 , taking the RNC requesting to report multiple LTE cells: load information of LTE cells 1-6, LTE cells 1-6 belong to multiple different eNBs, assuming that they belong to eNB1 and eNB2 as an example. Such as Figure 6 As shown, the first method in the first embodiment above may specifically include the following steps:

[0096] Step S501: The RNC of the UMTS system (hereinafter referred to as the source RNC) sends a RAN information request message to the SGSN to which it be...

Embodiment 3

[0116] The third embodiment describes the process in which the RNC requests the eNB to report the load information of its cell. The process of the eNB requesting the RNC to report the load information of its cell is similar to the third embodiment, except that the source node is replaced by the corresponding node of the LTE system, the destination node is replaced by the corresponding node of the UMTS system, and the message name is changed accordingly. I won't go into details here. see below Figure 7 , taking RNC requesting to report multiple LTE cells: load information of LTE cells 1-6, LTE cells 1-6 belong to multiple different eNBs, assuming that they belong to eNB1 and eNB2, and eNB1 and eNB2 belong to the same TAI as an example. Such as Figure 7 As shown, the first method in the first embodiment above may specifically include the following steps:

[0117] Step S601: The RNC of the UMTS system (hereinafter referred to as the source RNC) sends a RAN information reques...

Abstract

The invention discloses a load reporting method between a UMTS system and an LTE system and the LTE system. The method comprises the following steps: an RNC of the UMTS system sends an RAN message request message to an eNB of the LTE system, wherein the RAN message request message comprises RIM routing information and an RIM container, target cell information indicated by the RIM routing information being eNB identification of a plurality of eNBs or TAI belonging to the plurality of eNBs; the eNB returns an RAN message response message to an MME, wherein the RAN message response message carries CGI and load information of LTE cells belonging to the eNB; and the MME sends the RAN message response message to the RNC. The method and system in the invention help to reduce the influence on a core network, reduce the burden of the core network, reduce load report delay, and improve the network efficiency.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a load reporting method between a UMTS system and an LTE system and the LTE system. Background technique [0002] Modern mobile communication technologies tend to provide users with high-speed multimedia services, among which UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) and LTE (Long Term Evolution, Long Term Evolution) are more typical. [0003] figure 1 It is a system architecture diagram of the LTE system. next to figure 1 The various components of the LTE system shown are introduced: [0004] UE (User Equipment, user equipment) 101 is a terminal device used to receive data. [0005] E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) 102 is a radio access network, including: a macro base station (eNodeB (eNB for short) / NodeB ), the macro base st...
